DVWP MaximumRows ParameterBinding not working

Question

Is it possible to use ParamaterBinding for MaximumRows?

The following does not work.

Following set in SelectParmaters

<webpartpages:DataFormParameter ParameterKey="MaximumRows" PropertyName="ParameterValues" DefaultValue="1" Name="MaximumRows"></webpartpages:DataFormParameter>

Following bindings configured

<property name="ParameterBindings" type="string">
<ParameterBinding Name="MaximumRows" DefaultValue="3"/>
</property>

Changing the binding as you can see has no impact at all on the webpart. It remains showing 1 as set in the default.

This paramaterbinding works fine for WebUrl and ListName but seems to not work for MaximumRows. Can others confirm?

Thanks

One option is to aggregate the XSLTListViewWebPart, like this:

var xlcwp = new XsltListViewWebPart { ListId = myList.ID };
var ds = xlcwp.DataSource as SPDataSource;
if (ds == null) return;

var maximumRows = ds.SelectParameters["MaximumRows"];
if (maximumRows == null) return;

maximumRows.DefaultValue = "3";
